AW: [opencms-dev] problem to export database in .zip file

[Stephan Hartmann]

Hi Martin,

the IBM JDK 1.3 may be one of the fastest but is far away from being the most 
stable. I even got a stack overflow just when starting and stopping an empty 
jboss. For Linux the Blackdown JDK 1.3.1 seems to be the most stable but also 
the slowest.

Bye,
Stephan
